Dynamic Resource Allocation (DRA) has been introduced in Kubernetes 1.26 as an alpha feature. NVIDIA is targeting end of Q3 for the enablement of DRA in their GPU Operator, which would align on OCP 4.14. And their MIG-backed vGPU capability will likely be based on DRA.

On the OpenShift Virt side, Fabian Deutsch has created the CNV-24730 epic to track the work on DRA usage for VMs, with MIG-backed vGPU as a focus. And we are in touch with Kevin Klues on the NVIDIA side who is the co-author of the KEP and maintainer of NVIDIA DRA driver for GPU.

Having Dynamic Resource Allocation available in OpenShift 4.13, possibly behind a feature gate, would allow us to experiment on the implementation in OpenShift Virtualization.
